CYLINDER FOR "WASHING-MACHINES.

Specification of Letters Patent.

latented Jan, 2 2, acre.

Application filed. August 7, 1916. SerialNo. 113,451.

To all whom it may concern:

Be it known that I, LAWRENCE WrMAM- Minna citizen of the UnitedStates, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Cylinders for lashing-Machines, of which the following is a full,- clear, and exact specification, as will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to laundry washing machines of the rotating cylinder container type, having reference more particularly to the cylinder container itself, and has for one of its main objects to improve the construction and increase the efficiency and utility of machines of this type. Another object is to provide a-simple, compact and durable cyl- 'inder container. capable of being readily'and cheaply manufactured, and one constructed to obviate the necessity for removing the cylinder when the interior of the body of the machine is to be cleaned.

An important feature of my invention is the provision of a cylinder container havin oppositely disposed convex and concave si es presenting alternately perforated and solid ribbed walls to the contents thereof in the rotation of the cylinder, wherein suction chambers are arranged adjacent lines of juncture between said walls whereby to induce a powerful suction'through the per-,

forated wall portions and thereby increase the washing efi'ect of the cylinder, in its ro tation.

My "invention further contemplates the provision in a rotary cylinder container of means for preventing the balling-of the clothes in the container, that is, a means, designed to overcome any incipient rolling up These, together with such other objects as may hereinafter appear, or are incident to my invention, I at ain by means of the construction illustrated in preferred form in the accompanying drawings, tram- I Figure '1 is a vertical longitudinal sectional view of a washing machine embodying my invention; 7

Fig. 2 represents a vertical transverse section taken centrally through Fig. 1; V

Fig. 3 is a view in perspective of the cylinder container with the removable side sec tions disassociated.

Referring to the drawings, the numeral 4:"

designates the body portion of the washing machine which isprovided with a suitable cover 5 and legs 6, and within. this body 4% is journaled the cylinder containerprovided with suitable connections with the crank 7.

From an inspection of Figs. 1 and 2 it will be seen that the heads i of. the machine body 4, which are solid throughout and entirely close the ends of the same, are

provided substantially centrally thereof with fixed bearings 26 and 27 adapted to receive the stub shafts 28 and 29 of the cylinder, the former of which is preferably provided with a gear 30 in mesh with the crank shaft pinion 7,. These heads are desirably" formed of wood and to their edge portions is attached the metallic main body portion of the clothes into a ball due to rotation of' the container too long in one direction, and

without resorting to the heretofore common practice of alternating thedirections of rotation. This object is effected by providing novel bafiie or deflecting means disposed in thepath of the clothes to breakup the halling and which also incidentally permits the operator to simply rotate the machine in one direction only gflhich is formed in one piece, the whole being lealcproof and extending upwardly past the top line of the cylinder, terminating in a horizontal top opening adapted to be closed by the cover lid 5.

The numeral 8 indicates the heads of the cylinder formed with. concave and convex portions at diametrically opposite sides and provided at the jointurcs or corners of such portions with the perforated angularly disposed bars 9 and 10 secured'in juxtaposition to and extending between the heads 8. Imperforate concave wall sections 11 are attach'ed to the concave portions of the heads intermediately of the bars 1'6, and are each formed with a corrugated inner surface 12 in which the corrugations parallel the cylinder axis. r

In each convex portion, preferably one of the corner bars 9 is provided with wing nuts 13' and the other corner hair 9 pref erably has associated with it another similarly perforate bar 14 secured to the heads.

- Engaging each of the convex portions of the heads and fitting in between one of the bars 9 withits wing nuts and a bar 14: is a perforate wall section 15, both of which comprise slats formed with the several holes 16, and constitute diametrically opposite doors. Each of said doors in the embodiment shown have inner cross pieces 17 at its ends and to which the slats'composing the door are secured, the cross pieces projecting beyond one side of the door, as at 17, to terminally engage the under face of the bar 14, and the other marginal side of the door 18 and 19 are provided in the doors, and in the embodiment shown, each is diagonally mounted across a door to extend between opposite ends of its cross-pieces 17, the baflie members being so disposed diagonally with reference to each other, as in the manner clearly indicated in Fig. 3.. Furthermore, these members relatively have reversel curved rojecting face portions, the baflfri 18 on t e onehand having a central perforate ridge 20 and reduced end portions 21 and the bafiie 19 on the other hand is formed with the central reduced portion 22 and the perforate end ridges 23. As thus described, these ridges and reduced portions of the baflie members-have been formed to cooperate in a very eflicient manner in preventing any balling of theclothes, and as the bafiies are perforate they do not obstruct the'fiow of the cleansing liquid to any appreciable extent.

During the rotation of the cylinder the concave sections 11 form rubbing surfaces, and in passing through the water induce a flow orsuction through the holes in the doors, so that the fluid is drawn through the clothes with considerable force, the suction being augmented by the disturbance or deflected flow produced by the concave sections and still further increased by the provision of suction channels 24 formed by the longitudinal corner ribs 25 carried radiallyiby the bars 9 in juxtaposition to and substantially parallel with the bars 10 (Fig. 2). These channels 24 communicate with the holes formed in the bars 9 and 10 (Fig. 3). A cylinder so constructed and arranged will, in the operation of washing clothes, have a rapid and very effective action. It will be noted that these radial ribs, 25, direct a flow toward the corrugations of the concave sections 11 where the rubbing effect on the i clothes is produced. Another advantageous feature of my construction resides in the provision of the two removable door sec recover articles of clothing, without necessitating the lifting out of the container every time when this has to be done.

From the foregoing, the essential features,

elements and operation of my improved device, together {with its simplicity and other advantages thereof, will be clearly apparent to those skilled in the art.

I do not desire to be understood as limiting myself to the precise details of construction and arrangement shown, as variations and modifications may be .made' in the features of construction and arrangement without departing from the spirit and scope of my invention and the terms of the following claims.

What I claim is:-
